The locking piece 21 is set to protrude toward the indoor side a little further than the side wall 18. The locking piece 21 engages with the opening edge of the airtight rubber mounting groove of the indoor frame piece with the top surface of the stopper main body 7 in contact with the ceiling wall of the upper frame, and is covered by the indoor frame piece. It is designed so that In the drawing, a stepped portion 23 is provided on the left end surface side of the side wall 22 on the outdoor side;
This is a type of relief that accommodates a protrusion (not shown), and is not related to the gist of the present application.

In order to fit the stopper 6 of the present invention as described above into a predetermined position on the upper frame 4, the left end surface 8 of the stopper 6 is brought into contact with the vertical frame 2, and the inner shoji rail 12 is inserted into the fitting groove 13. Strongly push the stopper 6 upwards as shown in Fig. 5 by hand.
By this pushing-up operation, the inner shoji rail 12 fits into the fitting groove 13 and is strongly held by the clamping walls 9 and 10. On the other hand, while each of the locking pieces 16 and 21 is being pushed up, the locking pieces 16 and 21 are connected to the indoor side opening edge 25 of the retaining mounting groove 24 of the ceiling wall and the mounting groove 2 of the airtight rubber for the inner sash.
